| The touch plate is contacting a conductive workpiece, like aluminum. The touch plate signal is grounded through the material and machine frame, causing an active signal. | Use a thin non-conductive material to isolate the touch plate from the workpiece and other conductive materials, like vices. |
| The magnet is still contacting the touch plate. | Attach the magnet to the tool and retry the Auto Z procedure. More information: |
